CAR-AXLE BOX.

EPECIFICATION forming part of Letters Patent No. 318,520, dated May 26, 1885.

7 Application filed July 16, 1884. (No model.)

To all whont it may concern.-

Be it known that I, THOMAS THATCHER, a citizen of the United States, and a resident of the city of Utica, county of Oneida, and State of New York, have invented a new and useful Improvement in Axle End-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying draw- 10 ings ,and to letters and figures marked thereon.

Myinvention relates to an axle end-bearing for car and locomotive trucks; and it consists in the mechanism hereinafter described.

In the accompanying drawings, Figure l represents a longitudinal section of the axle, collar, end bearing, journal-bearing cap, and oil-box, taken at line a: m, Fig. 2. Fig. 2 represents an end View of the axle and end-bearing, with section of oil-box cut away, taken at line 3/ y. Fig. 3 represents a perspective view of the disk, and Fig. 4 represents a perspective view of the seat or support.

Having described my invention by reference to the figures in the accompanying draw- 2 ings, I will proceed to describe it by reference to the letters marked thereon,in which similar letters refer to corresponding parts throughout the several views.

or represents the journal of the axle of a cartruck. a represents the ordinary collar turned on the end ofsame.

a represents the journal-bearing. a represents the cap to the same. or represents the oil-box, which incloses the same.

3 5 a represents the projecting lug on the upper portion of the oil-box,to which a lid is ordinarily attached.

Heretofore the end-th rust and the lateral motion of the car and truck have been taken by the 0 collar and journal-bearing, resulting in friction and rapid wear, producing heated jour nals and creating an excessive lateral motion in the car and truck. To obviate these difficulties I have provided an end-bearing.

I accomplish this by means of a disk formed of steel or other suitable metal, supported in the oil-box opposite and in proximity to the end of the axle, so located as to receive the endthrust of the same. The disk is attached to and supported by aseat held in the oil-box by a bolt passing through the walls of the oil-box and through the seat, thereby allowing the disk and seat to move onits axis formed by the pivotal retaining-bolt.

In the drawings the disk and seat are formed separately. They may be formed together and held by a pivotal retaining-bolt, as before stated.

In the drawings, 1) represents the disk, riveted or bolted at b b to the seat 6, which is held in place in the oil-box by pivotal retain ing-bolt c", which passes through the walls of the oilbox and aperture 0 in the seat, thus allowing the disk and seat to adjust itself on its axis formed by the pivotal retaining-bolt to the end of the axle for receiving the endthrust thereof.

Although a collar is shown in the accompanying drawings, my invention can be used on axles with or without collars.

A concurrent application is herewith made by me for a patent for an improvement in an axle end-bearing for car and locomotive trucks, for one or more disks adapted to take the end-thrust, and to rotate when in contact with the end of the axle.

I do not claim in this application a rotating disk.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The herein-described axle end-bearing for car and locomotive trucks, having a disk held to a seat supported in the oil-box in proximity to and opposite the end of the axle by a pivotal retaining-bolt passing through the walls of the oil-box and seat,for adjusting the disk and receiving the end-thrust of the axle, combined and arranged as described, for the purposes stated.

Signed at Utica, New York, this 14th day of 9 July, 1884.

THOMAS THATOHER.
